Abstract: Materials, components, and methods consistent with the present invention are directed to the fabrication and use of micro-scale channels with a fluid, where the temperature and flow of the fluid is controlled through the geometry of the micro-scale channel and the configuration of at least a portion of the wall of the micro-scale channel and the constituent particles that make up the fluid. Moreover, the wall of the micro-scale channel and the constituent particles are configured such that collisions between the constituent particles and the wall are substantially specular.

Abstract: A cryogenic pump has an associated heater for vaporizing cryogenic fluid. The heater has a chamber (bounded by an inner sleeve and an outer sleeve) disposed around at least a portion of the pump housing. The heater has a helical heating coil with a plurality of turns disposed within the chamber and a helical baffle having a plurality of turns interspaced with the turns of the heating coil for guiding heat exchange fluid over the turns of the heat exchange coil. The heater has an inlet for cryogenic fluid to communicate with the heat exchange coil and an outlet for the resulting vaporized fluid. Heat exchange fluid flows through an inlet of the heater chamber to an outlet of the heater chamber and then through a space defined between the inner sleeve and a portion of the pump housing.

The vacuum indicator comprises an elongated tubular member for disposal in a vacuum line between the vacuum pump and a housing which is to be evacuated, the tubular member being made of an elastic material, with a wall of the tubular member having a uniform thickness of greater than 1/5 of an inside radius of the tubular member.

Abstract: A vaporizer apparatus includes a pump housing, a main housing containing an evacuation chamber, and an operation unit attached to the main housing. The operation unit selectively seals the evacuation chamber off from communication with an air inlet. One or more pumps in the pump housing is/are operable to generate a vacuum in the evacuation chamber. A mouthpiece is attached to the main housing, and may be selectively placed in communication with the evacuation chamber. When oil is placed in the evacuation chamber and the operation unit is operated, the evacuation chamber is temporarily sealed off from the inlet, creating a vacuum sealed chamber connected with the pump(s). Then, the pump(s) is/are activated to reduce pressure in the evacuation chamber, and the oil is vaporized at an ambient temperature without requiring a heater. When the operation unit is released, the evacuation chamber is emptied via the mouthpiece.

Abstract: A microfabricated gas flow structure includes an array of vertical gas flow channels in a side-by-side parallel flow arrangement. Adjacent gas flow channels are separated by a thin wall having a thickness which can be an order of magnitude or more less than the channel width, offering exceptionally high area efficiency for the array. Channel walls can be formed from a dielectric material to provide the walls with sufficient integrity at nanoscale thicknesses and to provide thermal insulative properties in the lateral direction, thereby controlling power losses when the gas flow structure is employed as a Knudsen pump. The gas flow structure can be microfabricated as a monolithic structure from an SOI wafer, with the gas flow channels formed in the device layer and the heat sink formed from the handle layer.
